2 the light dependent phase and the Calvin Cycle
It is the calvin cycle. It is the second step of photosynthesis.
carbon dioxide
The Calvin cycle itself does not need light.The Calvin cycle, also called the light independent stage of photosynthesis, uses ATP (energy) and NADPH (hydrogen) to convert carbon dioxide into carbohydrate (sugar). These reactions do not need light and can take place in the dark.However in a plant the ATP and NADPH are produced by the light-dependent stage of photosynthesis. To produce these substances light is needed.So although the Calvin cycle does not need light itself it does need substances made using light.See What_connects_the_light_dependent_reaction_to_the_light_independent_reactionand How_do_the_lightdependent_reactions_differ_from_the_calvin_cycle
